..aeruginosa pilA mutant was associated with TLR4 induction and indicated that nonpilus adhesin-induced signaling was repressed by TLR2 function and, if not blocked by the host, could induce airway hyperresponsiveness...

Toll-like receptor 4 (TLR4)-deficient murine macrophage cell line as an in vitro assay system to show TLR4-independent signaling of Bacteroides fragilis lipopolysaccharide

..influenzae can favor signaling through non-TLR4 receptors, such as TLR2. The results also indicate a close interaction between TLR4 and TLR2 that tightly regulates the expression of both receptors...

Relevance of mutations in the TLR4 receptor in patients with gram-negative septic shock

..We determined whether recently discovered genetic variants of toll-like receptor 4 (TLR4) that confer differences in the inflammatory response elicited by bacterial lipopolysaccharide are related to the development of atherosclerosis...

Up-regulation of S100A8 and S100A9 protein in bronchial epithelial cells by lipopolysaccharide
